[pacman-dev] pacman problems

[antonio.grande at uniroma1.it]

I'am a newbie so please thank you for your patience.
Executing
pacman -S samba
I've this
error: failed retriving file 'tdb-1.2.0-1-i686.pkg.tar.gz'
But both two mirrors I've in my etc/pacman.d/mirrorlist contain the filename "tdb-1.2.1-1-i686.pkg.tar.xz" where there is a
difference about the version 1.2.1 and also in the extension .xz instead of .gz
My pacman version is 3.3.3-1 which is the latest. Someone can help me? Thank you. Antonio Grande
